5. Cut your home phone bills
BT used to be called British Telecommunications but shortened it after a survey found that only 4% of school leavers could spell telecommunications, while 6% could spell BT - even if they believed it was a sandwich without the lettuce. It was also shortened to reflect its habit of charging more and more for less and less. It owned the infrastructure it could do what it liked. If you must use your phone there are scores of cheaper alternatives that package your telephone, television and broadband access, some that offer low-cost alternatives using your existing BT line.
